You are considering three investment options. The first is a stock fund, the second is a corporate bond fund, and the third is a T-bill money market fund (the risk-free asset) that yields a sure rate of 5.5%. The probability distributions of the risky funds are:

Expected return (%) Standard Deviation (%)

Stock fund (S) 15 32

Bond fund (B) 9 23

The correlation between the fund returns is 0.15.

What is the portfolio weight for the bond fund in the optimal risky portfolio?

Your answer should be in decimal values and accurate to the hundredth (NOT in percentage points).
